Use this skill

Save it into your project's skills folder. Claude Code picks it up in its next session.

curl -fsSL --create-dirs -o .claude/skills/xu-xiang-tdd-workflow/SKILL.md https://app.decimal.ai/s/xu-xiang-tdd-workflow/SKILL.md

Want it pinned and updatable? pip install "decimalai>=0.15", then decimalai skills add xu-xiang-tdd-workflow, and start Claude Code with claude --plugin-dir "$(git rev-parse --show-toplevel)/.agents"

1 · One-time — install the CLI (docs ↗)

pip install "decimalai>=0.15"

2 · Get the skill — writes .agents/skills/xu-xiang-tdd-workflow/ and pins it in .decimal/skills.lock

測試驅動開發工作流程

此技能確保所有程式碼開發遵循 TDD 原則，並具有完整的測試覆蓋率。

何時啟用

撰寫新功能或功能性程式碼
修復 Bug 或問題
重構現有程式碼
新增 API 端點
建立新元件

核心原則

1. 測試先於程式碼

總是先寫測試，然後實作程式碼使測試通過。

2. 覆蓋率要求

最低 80% 覆蓋率（單元 + 整合 + E2E）
涵蓋所有邊界案例
測試錯誤情境
驗證邊界條件

3. 測試類型

單元測試

個別函式和工具
元件邏輯
純函式
輔助函式和工具

整合測試

API 端點
資料庫操作
服務互動
外部 API 呼叫

E2E 測試（Playwright）

關鍵使用者流程
完整工作流程
